SPEQIFIGATION forming part of Letters Patent N 0. 728,508, dated May 19,1903. Application filed November 26, 1902 Serial No. 132,852. (Nomodel.)

To all whom it may concern;-

Be it known that I, HATTIE M, SHIELDS, a

' citizen of theUnited States, residing at Indianapolis, in the countyof Marion and State of Indiana, have invented new and usefulImprovements in Stovepipes for Flue-Cleanin g; and I do declare thefollowing to be a full, clear, and exact description of the invention,reference being had to the accompanying drawings, and to the letters ofreference marked thereon, which form a partof this specification.

Myinven tion relates to flue-cleaners for domestic use, and it hasreference particularly to devices whereby the bottoms of chimneyfiuesthat have stovepipes connected therewith may be cleaned and also wherebythe stovepipe portions of the flues may be cleaned without taking themdown from their positions.

The object of the inventionis to provide means whereby flues maybecleaned while the stoves or furnaces connected therewith have fires inthem and without causing dust to arise in the atmosphere of the roomsand also without causing soot to fall upon the My invention consists ina stovepipe-elbow having a novel form of opening and a door therefor;and the invention consists also in. the novel parts and the combinationand arrangement of parts, as hereinafter particularly described andclaimed.

Referring to the drawings, Figure l represents a cooking-stove inelevation and a stovepipe having'my improvements and a portion ofachimney in central vertical section connected with the stove, showing ascraper in operative position in the pipe; Fig.2, a perspective view ofa scraper; Fig. 3, a perspective View of a portion of the extensionhandle-rod of the scraper; Fig.4, a perspective View of portions of theh'andle-rods, showing the means by which the two parts of the rod areconnected together; Fig. 5, a perspective view of the latch-plate forthe door of the elbow-opening; Fig. 6, a fragmentary perspective view ofthe elbow, showing the door latched thereon; Fig. 7, a fragmentarysectional view of the elbow, showing the form of the latch-plate insection engaged by the door- Iplan view.of the elbow, showing the formof the opening therein.

In-the drawings, a designates the stove, in the construction of whichprovision is made for removing soot from the bottom thereof, there beingpassages, as usual, through which soot from the vertical portion b ofthe stovepipe'may fall to the bottom of the stove. The pipepart I;usually has a damper 01 therein. At the top of the part b is an elbow A,having an opening Bin the portion thereof at the outer side of its curveor so situated that a line entering either end of the elbow may passthrough the opening. A horizontal portion e of the pipe connects theelbow with the flue got the chimneyf. In forming the elbowA 7c a centralsection h is usually employed'in connection with a suitable number ofsections at the sides thereof, and the opening B is most convenientlycut in the central section h. At the upper side of the opening a smallrecess 11 is cut in the metal, and alike recess j is cut in the metal atthe opposite or lower sideiof the opening. A door properly adjusted. Thedoorhas a latch l,

normallly engaging a latch-plateD, secured to the metal adjacently tothe side of the opening opposite to the rivet k, the latch-plate havingthree notches m, 'n, and 0, either of which may be used in adjusting thedoor 0 in its several possible latched positions. The latch-plate may bemade either of sheet metal or of bent wire, as will be obvious, or asalight casting. I A suitable scraper E in plan is-of the fa- 5 miliarcrescent shape, the convex edge being adapted to scrape the concave formof the interior of the flue or pipe and the concave edge being designedto clear the central portion of the damper and also to clear the sootwhen inserting the scraper into the pipe. The scraper has a suitablehandle-rod which is preferably extensible andwhen so made comprises arod F, attached at one end to the scraper and having at the opposite endthereof a side loop G, through which a rod H extends parallel to the rodF. A sliding collar I extends about the two rods between the scraper andthe loop G and has a set-screw adapted to engage the rod F. The loop isattached to the rod H suitably, as by means of a hook J, turned over atthe end of the rod about the adjacent portion of the collar. Theopposite end of the rod H has a handle q of suitable form.

In practical use the scraper may be operated somewhat as indicated inFig. 1, wherein it is shown in full lines and also in dotted or brokenlines, illustrating the positions in which it may be operated, thehandle-rod working in the recess j or the recess i, as cir cumstancesmay require, the door 0 being so latched that the proper recess may beuncovcred.

Having thus described my invention, what I claim is- A pipe-elbow havingan opening in the wall thereof provided with recesses at opposite sidesthereof, a latch-plate attached to the elbow and having a plurality ofnotches, a door pivoted to the elbow adapted to cover the opening andthe recesses, and a latch attached to the door and adapted to cooperatewith either one of the notches in the latchplate.

In testimony whereof I affix my signature in presence of two Witnesses.
